Response-surface-model-based system sizing for nearly/net zero energy buildings under uncertainty [PDF]

, 2018
Properly treating uncertainty is critical for robust system sizing of nearly/net zero energy buildings (ZEBs). To treat uncertainty, the conventional method conducts Monte Carlo simulations for thousands of possible design options, which inevitably leads
